Patent number: 8684938Abstract: A biological condition evaluation apparatus determines a symptom of a heart abnormality based on at least one index calculated from a heartbeat interval and/or a pulse interval. The apparatus determines whether it is in a referential period where an amount of change in the index is comparatively small. The apparatus determines whether a plurality of conditions are satisfied or not in an evaluation period set after the referential period. One condition is that an amount of change in the index in the evaluation period is greater than that observed during the referential period. Another condition is that a rate of change in the index is equal to or greater than a predetermined threshold value. The apparatus determines that there is a symptom of a heart abnormality, when both the conditions are satisfied.Type: GrantFiled: January 18, 2010Date of Patent: April 1, 2014Assignees: DENSO CORPORATION, Nippon Medical School Foundation, Toyota Jidosha Kabushiki KaishaInventors: Kazuhiro Sakai, Shinji Nanba, Takao Katoh, Motohisa Osaka, Yoshitaka Fuwamoto

Patent number: 7945313Abstract: An heart rhythm monitoring device for a vehicle, which determines whether a driver has an arrhythmia includes a vehicle state determining portion that determines whether the vehicle is stopped; an electrode arranged on a steering wheel in a position where the driver grips the steering wheel; an electrocardiogram waveform obtaining portion that obtains a first electrocardiogram waveform from the electrode; and a signal processing and calculating portion that determines whether the heart rhythm of the driver is erratic based on the first electrocardiogram waveform. When the vehicle is in motion, the signal processing and calculating portion determines whether the heart rhythm of the driver is erratic based on the waveform component that is strong with respect to noise in the first electrocardiogram waveform.Type: GrantFiled: May 10, 2007Date of Patent: May 17, 2011Assignees: Toyota Jidosha Kabushiki Kaisha, Nippon Medical School Foundation, Denso CorporationInventors: Yoshitaka Fuwamoto, Takao Katoh, Tsuyoshi Nakagawa, Taiji Kawachi
